For the sake of completeness, I found my error.

I assumed, due to the writing on the back, that the ports must be 21/22. However, the SDA/SCL ports for the groove port are 32/33.

while (!scales.begin(&Wire, 32, 33, DEVICE_DEFAULT_ADDR)) { Serial.println("scales connect error"); M5.Lcd.print("scales connect error"); delay(1000); }

Changing the ports in the scales.begin fixed the error.

Greetings Pascal

@PascalS Now I see the problem.
Wire is hard defined and set to internal.

You need to use Wire1 to access the external devices.
I vaguely remember reading about this issue before but as I don't have arduino I had forgotten about it.
Thanks for the reminder.
